    ABSTRACT: Accident and emergency (A&E) departments experience a secondary peak in patient length of stay (LoS) at around four hours, caused by the coping strategies used to meet the operational standards imposed by government. The aim of this paper is to build a discrete-event simulation model that captures the coping strategies and more accurately reflects the processes that occur within an A&E department. A discrete-event simulation (DES) model was used to capture the A&E process at a UK hospital and record the LoS for each patient. Input data on 4,150 arrivals over three one-week periods and staffing levels was obtained from hospital records, while output data were compared with the corresponding records. Expert opinion was used to generate the pathways and model the decision-making processes. The authors were able to replicate accurately the LoS distribution for the hospital. The model was then applied to a second configuration that had been trialled there; again, the results also reflected the experiences of the hospital. This demonstrates that the coping strategies, such as re-prioritising patients based on current length of time in the department, employed in A&E departments have an impact on LoS of patients and therefore need to be considered when building predictive models if confidence in the results is to be justified. As far as the authors are aware this is the first time that these coping strategies have been included within a simulation model, and therefore the first time that the peak around the four hours has been analysed so accurately using a model.

    ABSTRACT: Using a case study as an example, this paper illustrates the current model of care in Accident and Emergency (A & E); in particular, the 'cells' in which data/information is stored and how explicit and accessible it is (or is not) to healthcare professionals. It is a model of care which may be summed up as static information/dynamic clinicians. This paper then describes how mobile devices may be used to track patients through an A&E department. From there, a model of care is proposed that has at its core the notion of dynamic information/static clinicians which takes into account the potential and likelihood of such mobile technology being used to support healthcare professionals in the future. It is argued, however, that such 'disruptive technologies' are merely tools at our disposal and that it is human activity which must be foremost when considering how we might work differently ('better') in treating and/or dealing with patients.
